The trust problem solved the design problem
We researched with parents aged 25–46 and found genuine disagreement — some felt teen autonomy was essential, others wanted full visibility. The deciding insight was what I call the trust problem: no abusive parent downloads an app that limits their access. So the system can safely grant teens real privacy, because the people most likely to misuse oversight self-select out.
The edge case that drove the design: a teenager dealing with substance use who can't talk to their family — that's exactly the user who needs the confidential chat most.
“No abusive parent downloads an app that limits their access. That's why we could give teens genuine clinical privacy — the edge case we designed for was a teenager in crisis who can't speak to their family.”
